--Boundary_(ID_w+xTtUei45fRSwPSGezdDg) Content-type: text/plain; CHARSET=US-ASCII; delsp=yes; format=flowed Content-transfer-encoding: 7BIT Shawn, these jellyfish are almost certainly Moon Jellyfish, Aurelia aurita?, which is one of our two species of common Scyphozoan jellyfish in the North Atlantic. Moon Jellyfish do not sting us, but they have stinging cells for capturing very small prey like copepod crustaceans, fish larvae, planktonic worms, etc. Our other Scyphozoan jellyfish is the Lion's-Mane Jellyfish, Cyanea capillata?, which has very long reddish tentacles, is a notorious bad stinger for swimming humans and the jellyfish's prey animals, and reputedly can get enormous in arctic waters. Other kinds of jellyfishes occur in Nova Scotia, but most of them are quite small and harmless and are Hydrozoans, which are extremely common in the sessile colonial polyp stages in places like the mudflats of the Minas Basin. As an aside, the Nova Scotia Sea Turtle Network, based in Halifax, has been surveying beaches for a few years for noticeable jellyfishes, since they are prey themselves for more than one species of endangered sea turtles, especially the huge leatherback sea turtles.
